无水生物以其对极端环境条件的抵抗力而闻名，而这些生物处于不活跃的非代谢状态。这项研究证实，这种抗性也会转移到使用甲基溴熏蒸剂的处理上。在甲基溴处理70h后，发现了线虫、轮虫和迟缓虫的活标本。对瑞氏冠状冠层存活的定量估计表明，短期保持干燥的处理样本和未处理样本之间没有差别。然而，与治疗前不久收集的样本相比，治疗前11个月收集的样本中冠状杆菌的存活率较低。事实上，无论是对食品业还是从人为媒介的生物体传播的角度来看，都应该认为无水生物体逃脱了杀菌剂的处理是一个严重的问题。(C)2001年学术出版社。
Anhydrobiotic organisms are well known for their resistance to extreme environmental conditions while in the inactive, ametabolic, state. This study confirms that this resistance also transfers to treatments with the fumigant methyl bromide. Live specimens of nematodes, rotifers, and tardigrades were found after 70 h of treatment with methyl bromide. Quantitative estimates of survival in the eutardigrade Richtersitts coronifer revealed no difference between treated and untreated samples which had been kept dry for a short time. However, R. coronifer from samples collected 11 months before treatment had lower survival compared to samples collected shortly before the treatment. The fact that anhydrobiotic organisms escape treatments with biocides should be considered a serious problem, both for the food industry and from the perspective of human-mediated spread of organisms.
